Question

Quizplus · Accepted Answer

The mesial/distal, buccal/lingual hoe is designed to remove calculus with a pull stroke and does not crush calculus. A back-action hoe is used to remove bone adjacent to teeth without causing trauma. A periodontal probe does not remove calculus but measures sulcus and pocket depths. An interdental knife is designed to remove tissue, not calculus.
